`FREDERICK 'FRANKLIN DIER', or WINNIPEG, MANITOBA, CANADA.

GAS-LIGHTING `Itri?LIANQE'.

To all/whom' it may concern:

Be it known that I, `FREDERICK FRANKLIN DIER, f the city ofWVinnipeg, in the Prov-A ince of Manitoba, Canada, have invented. certain new' and useful Improvements in Gas- Lighting A pliances, of which the following is the spec' cation.

My .invention relates to an electrical device, but itinere particularly concerns improvements in electrical'igniting combinationfinfwhich the various part'sare devised so'that'thef may be conveniently assembled 1e 'The object'of the invention is .to provide an economical, simple, electrically, operated deviceby which gas can be ignited, the in.- vention eing particularly designed for use in connection with a' gas burner -as utilized in theordinary cooking gas-stove..

" A'iurther ob'ectihas been to so devise the appliance that there-is no .possibility of thel operator receiving an electric" shock when using.

In using gasy or gasolene stovesit has heretofore been necessary t'o resort tol matches as a means forigniting the burners of thesain'e I but 'this is' both costly,andinconvenient,` the operationof .igniting 'the burners carrying with it certain ossibilities of injury, byburning, to. the and, which might v Well be avoided.

' Accordin ly this invention has in view the provlsiono `a means whereby a gas burner can be ignited without the employment' of any combustible device, the Vgas' being,

, "ignited by an electric spark produced'in' the ath' ofthe Aesca ing gas from theb'urner,

through thev emp oyment lof a contact making instrument, the ap lica'tion of the ins'tru\ mehtto 4the metallic urnerclosin'g the circuit.

certain parts being shownin side elevation.

.-Fig.' 3 is va longitudinal cross sectionalview lthrough a portion of the tube forming the body of the instrument, the section being taken at right angles t'o the section as shownl in Fig. .2, and the operating parts therewithin appearlng'm lan. Fig. 4 is an enlarged vertical sectlona view through the boX showing a s ark coil and a battery.

nthe drawings like characters of reference' indicate corresponding yparts -in eachfigure.

1 represents a gas burner of anyiorm carried by the stove 2, the burner being connected with la gas supply pipe 3.

' 4 is a square box inwhich is placed two cells 5 and 6 forming a battery, the cells be-4 ing connected electrically by a wirel '7 secured to the binding post 8.- 9 is a helix or solenoid'also within thebojr, the solenoid ap pearing in the form of a spool and being formed from a soft iron core 10, end pieces'll,

5 and many turns of wire'12, such turns passing around the core from the binding post 13 to the binding post 14. The binding post 14. is electrically connected to the battery15 of thecell 5 by a wire 16.v

17` and 18 are binding posts within the box and secured to the under sideofthe top adjoining the bushings 19which pass through the top.- 'The binding post 17 is electrically 'connected with that 13 by a.wire 20, and the binding post 18 is connected to the binding post 21 of the cell 5 by a wire 22.

23 is a lead wire passing from the binding post 18 through the bushing 19 to the stove being placed i'n electrical contact therewith.

In the drawing the wire is connected to the- 'fsupply pipe 3 by winding it aroundthe pipe.

24. is the contactmaking hand instrument which consists in a lhandle formed from a tube 25, preferablyof metal, and of a length The tube has a longitudinal' slot 26l cut therein through which extends from the interior outwardly a ibrousmember 27 forming'a contact press button. The member is formedv with forwardly and rearwardlyl extending en d pieces 28 and29, respectively, the end piece 28 -having its-upper'. face somewhat rounded and receiving a screw 80 passing in-vv wardlyl from the tubing. wherebyzthemember.

der side, and a flat bent spring 39 is inserted .are inserted within the tube.

end piece.29 to which it is secured being vthereby'electrically insulated from the tube.

32 is a second plate immediately beneath the plate 31, such plate extending from a ibrous supporting block 33 iirmly secured to the tube and toward its end by a screw 34. The tube is closed at one end by a plate 35 there being a central opening in the plate in which is secured a coiled spring 36 which extends for a slight distance beyond the end. Within the coil spring is an insulated wire 37 the one end of which enters the tube and is electrically 'connected to the plate 32 at 37 and the other end of which passes to the post 17 through the bushing 19. The purpose of the spring coil is to protect the wire from unnecessary lWear, as will readily be understood.

The'inember 27 is recessed at 38 on its unwithin the recess bearing against the member and against the inner face ofthe tube thereby holding the member in its upper position which places the plates 31 and 32 out of contact. By depressing by the hand that portion of the member which'extends through the slot the plates are brought into electrical contact, and upon release of the -hand pressure the contact is broken by the action of the spring. y

40 is a paper fiber plug inserted in the open end of the tube and held securely in position by a screw 41.

42v is a resilient, metallic, conducting plate having its end embedded within the plug 40 so as to begcompletely insulated from the tube. The plate is placed in electrical contact with the plate 31 by a wire 43 which passes to the side of the member 27.

44 is a hook extending from the plate 35 wheeb y the instrument can be hung up if desire l It will be seen that the hand instrument can be readily put together when desired as the electrical connections between the va'- rious parts can all be made before the parts words the wire 43 is secured to the plate 42 and to the plate 31 and then the member 27 is inserted in the tube, the spring being previously placed in the recess. The member 27 is turned till it comes to the proper point where it is secured by the screw. The plug -40 is then fastened in position. The contact between the wire 37 and the plate 32 is made before the fiber block 33 is inserted, it being understood vthat the end of the tube is closed by the plate 35 after the block has been secured in position by the screw 34.

.In using the device the instrument is grasped by the hand, the plate 42 beingl In other brought into contact with the gas buri` r of the stove and at the same time the member 27 is depressed bringing the plates 31 and 32' into contact, thereby closing `the circuit.

I/Vith the plates' still in Contact the instrument is removed from the ourner and there is a llash or spark, which if the gas be turned on ignites it.

An important feature in connection with my appliance is that there is no possibility ol' a closed circuit when not desired. On account ol' the connection of the wire'23 with the stove a spark can be made by applying the plate 42 oi the instrument to the stove at almost any point and withdrawing it, the whole stove forming a conductor.

y Ii' the contact were not broken within the instrument and the portion not insulated from the tube the circuit would be 'closed if the tube'were carelessly left on the stove and the result would be harmful to the battery `in time.
